Sunderland are closing in on a second signing, with Celtic’s Adam Matthews reportedly undergoing a medical on Wearside.

The Black Cats are understood to have agreed a fee of £2m with the Scottish Premier League champions for the Wales international right-back.

And the 23-year-old is believed to have travelled to the North East yesterday to discuss personal terms and complete the move.

Matthews spent four years at Celtic, after joining on a free transfer from Cardiff City.

He has made almost 150 appearances for the Hoops in all competitions, scoring four goals, and he has been capped 12 times by Wales.

It is no secret that Sunderland have been seeking to add a right-back to their squad this summer, and they made a loan move for Arsenal’s Carl Jenkinson and were also understood to be considering a bid for Leeds United’s Sam Byram. But their move for Matthews suggests they will no longer pursue either Jenkinson or Byram.

SUNDERLAND will make their TV debut this season against Tottenham Hotspur in September.

The first tranche of televised fixtures has been released by broadcasters Sky Sports and BT Sport, covering Premier League matches up to the end of September, and the Black Cats’ home game against Spurs is their only appearance in front of the cameras, The game will move to Sunday, September 13, with kick-off at the Stadium of Light moving to 1.30pm.

And that means the fixture clashes with the Great North Run, which takes place on the same day.
